“…Guenther et al (1994) summarized the results of eight emission measurement studies and found that most leaflevel emission capacities for oaks (Quercus) fell within the range 70 g g\ h\ $50%, but there were several studies that reported much lower rates for at least some oak species. If growth environment and leaf age are nearly constant, then leaf-to-leaf variability is about 5% for a single tree , 10% for di!erent trees of the same clone (Isebrands et al, 1999), and about 25% for di!erent clones of the same genus (Isebrands et al, 1999). Benjamin et al (1996Benjamin et al ( ,1997 assigned di!erent isoprene emission capacities to a large number of plant species.…”

“…Five genera were assigned a high (70 g g\ h\) isoprene emission capacity and a low or moderate (14 or 35 g g\ h\) value was assigned to eight genera. Recent measurements indicate that all North American broadleaf isoprene-emitters on the Guenther et al (1994) list can have isoprene emission capacities that exceed 80 g g\ h\ (e.g., Harley et al, 1997;Isebrands et al, 1999). Plants with a leaf structure that contains fewer chloroplasts per foliar mass are expected to have a lower capacity for NMVOC emissions from chloroplasts.…”

“…Selected results from these studies have been reported (Greenberg et al, 1994;Guenther et al, 1996a;Isebrands et al, 1998). Here, we use data from the branch enclosure experiments reported by Helmig et al (1998) to derive landscape scale flux potentials at three sites using the results of extensive biomass surveys, ambient temperature and light data series, and scaling to measured landscape-level isopt~ae fluxes.…”

Biogenic volatile organic compound emissions (BVOCs) II. Landscape flux potentials from three continental sites in the U.S.

Landscape flux potentials for biogenic volatile organic compounds (BVOCs) were derived for three ecosystems in the continental U.S. (Fernbank Forest, Atlanta, GA; Willow Creel Rhinelander, WI; Temple Ridge, CO). Analytical data from branch enclosure measurements were combined with ecological survey data for plant species composition and biomaas. Other quantitative flux measurements at the leaf and landscape level were incorporated to scale the results from the enclosure measurements to the landscape level. Flux estimates were derived by using a one week ambient temperature and light record (30 rain time resolution) and adjusting all emission rates to these conditions with temperature and light correction algorithms. © 1999 Elsevier Science Ltd. All rights reserved Although uncertainties due to the branch enclosure technique limit the conclusions, tentative data which is valuable to define future re, search attention and nectis is derived. Scaled to the landscape level, this technique allowed identification of those plant species that arc responsible for the major fraction of the total BVOC landscape flux and to identify the major compounds ¢n~tted. It was found that for each of the sites investigated, a very few selected plant species contribute to the major fraction of the total emissions. Northern red oak, post oak, white oak and American beech accounted for 71% of the total BVOC emissions at the Atlanta site. Quaking aspen and Northern red oak were the dominating species at the Wisconsin site with 68% of the total emissions. At the Colorado site, Gambel oak and service berry made up 86% of the BVOC emissions. Total daily average BVOC landscape fluxes determined by this method were 2.0, 4.5 and 2.4 mgC m2h ~ for the Atlanta, Wisconsin and Colorado sites, respectively. The contribution of isoprene to this overall BVOC flux was calculated to be 45, 38 and 54% at the three sites, respectively.The branch enclosure technique combined with ecological surveying and landscape-scale isoprene flux measurements proved to be a valuable tool for seroerting a high number of plant species and for identifying the major . and most important emitters for a more thorough investigation. The obtained data, the suitability of this approach and its limitation to derive BVOC fluxes on the ecosystem level are critically evaluated and factors introducing experimental errors are identified.

“…The site is a mixed deciduous forest containing northern red oaks and big-tooth aspens, which are known to be strong emitters of isoprene and monoterpenes (Isebrands et al, 1999;Funk et al, 2005). A highway (E Matlock Road, State Route 45) is located 1 km southwest, and therefore the site can be impacted by anthropogenic emissions.…”

Development of an instrument for direct ozone production rate measurements: measurement reliability and current limitations

Abstract. Ground-level ozone (O 3 ) is an important pollutant that affects both global climate change and regional air quality, with the latter linked to detrimental effects on both human health and ecosystems. Ozone is not directly emitted in the atmosphere but is formed from chemical reactions involving volatile organic compounds (VOCs), nitrogen oxides (NO x = NO + NO 2 ) and sunlight. The photochemical nature of ozone makes the implementation of reduction strategies challenging and a good understanding of its formation chemistry is fundamental in order to develop efficient strategies of ozone reduction from mitigation measures of primary VOCs and NO x emissions.An instrument for direct measurements of ozone production rates (OPRs) was developed and deployed in the field as part of the IRRONIC (Indiana Radical, Reactivity and Ozone Production Intercomparison) field campaign. The OPR instrument is based on the principle of the previously published MOPS instrument (Measurement of Ozone Production Sensor) but using a different sampling design made of quartz flow tubes and a different O x (O 3 and NO 2 ) conversiondetection scheme composed of an O 3 -to-NO 2 conversion unit and a cavity attenuated phase shift spectroscopy (CAPS) NO 2 monitor. Tests performed in the laboratory and in the field, together with model simulations of the radical chemistry occurring inside the flow tubes, were used to assess (i) the reliability of the measurement principle and (ii) potential biases associated with OPR measurements. This publication reports the first field measurements made using this instrument to illustrate its performance. The results showed that a photo-enhanced loss of ozone inside the sampling flow tubes disturbs the measurements. This issue needs to be solved to be able to perform accurate ambient measurements of ozone production rates with the instrument described in this study. However, an attempt was made to investigate the OPR sensitivity to NO x by adding NO inside the instrument. This type of investigations allows checking whether our understanding of the turnover point between NO x -limited and NO x -saturated regimes of ozone production is well understood and does not require measuring ambient OPR but instead only probing the change in ozone production when NO is added. During IRRONIC, changes in ozone production rates ranging from the limit of detection (3σ ) of 6.2 ppbv h −1 up to 20 ppbv h −1 were observed when 6 ppbv of NO was added into the flow tubes.
